Specification of Letters Patent.

Patented June 13, 1911.

Application filed September 29. 1910. Serial No. 584,508.

To all whom it may concern:

Be it known that I. Axrox Mrrrzst.. a citizen of Austria. residing at Lonsdale. m

have invented certain new and useful Iniprorements in Safety-Stirrins; and I do, declare the following to be a all, clear, and E exact description 0 the invention, such as j will enable others skilled in the art to which it a ipertains to make and use the same.

This invention relates to an improved safety stirrup.

The object of the invention is to construct a simple and ellicicnt safety stirrup in which one or both side members will automatically open should a ruler fall from ltlS horse, and i 4 ribs 1' and 5 are spaced laterally from said thereby reliably protect him against being caught in the stirru and dragged.

With this and other objects in view, the invention consists of certain novel features of construction, combination and arnmgt ment of parts as will be more fullv described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of this improved stirrup, with the members in normal position: F ig. 2 is a longitudinal vertical section thereof; Fig. 3 is a transverse vertical section; Fig. 4 is a vertical section of the casing with the toe piece in place. Fig. 5 is a per- 5 iectire view of the other casing member; h ig. 6 is a detail perspective view of the free end of one of the foot sections; Fig. 7 is a similar view of the toe piece.

In the embodiment illustrated, the stirrup includes a hanger section 1 and a foot su porting section 2, the two being detachalny united by a catch mechanism hereinafter to be described. which mechanism is tripped or released by the movementof a toe piece 3. 5

isaid pins. 'hen in this [)OSlt l0ll the pins Espring forwardly through said apertures The foot support 2 is composed of two substantially L-shaped twin sections 4 and 5, with their short arms hingedly connected 3 if the casing. Arranged on the other side of the )tllilI-IOH 17 IS a chamber 24 In which exat their free ends as shown at 6. The inner faces of the short arms of these L-shapcd members are provided with recesses 7 and 5 secured to the toe-piece 3. Stll toe-piece being 8 to receive the opposite ends of an upwardlv bowed plate spring 9 which is con- I intermediately of its ends to the 3 lower face of a foot lever or plate 10 which fixed to the upper or free end of said plate.

nectc late is pivotally connected intermediate of its ends to the pintlc of the hinge connec- I l face of the plate 27 through an aperture tion 6. This spring 9 tends to force the members 4 and 5 into open position and I 5 and a coiled spring 29 is arranged on this causes them to spring apart when the upper ends thereof are disengaged from the catch mechanism which locks them to other. Two

I lugs 11 and 12 project latcra 1y from the the county of Rice and State of Minnesota.

f bers 4 and 5 intermcdiately of the width inner faces of the upper ends of the m mthereof and are provided with catch regeiring apertures as 13. and also with auxiliary apertures'as 14 preferably of smaller size, and which are designed to receive lockl ing screws as 15 t hich secure them against t' fr th I 5 cpaia ion om e ianger member. The inner faces of the upper ends of the members 4 and 5 are preferably provided with longitudinally extending ribs 4' and 4" and 5 and 5", respectively, which are arran ed on opposite sides of the lugs 11 and 12. The

lpgs a Sllllltltlllt distance to permit the insertion between said ribs and lugs, of the flanges of the hanger section to be described, when the parts are in operative position. The free ends of these lugs 11 and 12 are preferably beveled to facilitate their insertion within the casing in a manner hereinafter to be described.

The hanger section 1 comprises a plate having a strap 100 10 at its upper end and with its lower en extended to form a cen tral partition 17 in the casing 19, which carries the catch mechanism. This partition 17 is provided with a plurality of transrelselv spaced apertures as 20 through which catci pins as 21 and 22 carried by the toe piece 3 are adapted to operate. Atone side of this partition 17 is formed a. chamber 23 open at its opposite ends to receive lugs 11 and 12 of the foot supporting member. \Vhen the beveled ends of these lags are forced into said easini, they cause the pins 21 and 2-2 to spr'nig ackwardly until the apertures 13 in said lugsregister with and lock the lugs 11 and 12 securely within tents the free end of an 11 right plate 27 preferably made arc-shaped, as shown. Pins 21 and '22 project at 11 ht angles from one face of laterally eaten mg arms 25 and 26 A stud 28 projects laterally from the outer formed in the outer wall of the chamber 24,

stud between the inner faces of the outer wall of said chamber 24 and outer face of said plate 27, and exerts its tension to force the ins 21 and 22 normally through the 5 partition 17 into locking position within the chamber 23. This stud 28 is preferably connected with said plate by being screwed therein and is provided at its outer end with a kerf for inserting and remov' it, as shown in F'g. 1. The n er end the plate 27 is pre erably provn ed with laterally projecting outwardly extending lugs 30, preferably formed by bending the c0rnets of said plate to form stops for limiting the outward movement of the stud 28, The members of the casing 19 are detachably connected together and to the partition 17 by means of screws or any other suitable fastening devices. The chamber 24 is provided at its opposite ends with flanges as 24* which lie in close contact with the adjacent. face of the partition 17 near its side edges, the edges of said plate and said flanges extending into the space between the ribs 4 and 5 and the lugs 11 and 12 of the members 4 and 5. Right angular flan es as 23 are formed on the end walls of c chamber 23 below and above the openings therein, and these flan 'es 23 abut against the ribs 4" and 5" of the members 4 and 5 when the parts are in operative position The outer wall of the chamber 23 is providcd with apertures as 31 which are designed to register with similar apertures as 14 in the lugs 11 and 12 to receive the screws as 15, which may be used for looking the side members of the stirrup against automatic separation.

If desired, one side member of the foot supporting section may be locked against opening by one of the screws 15, or both may be locked it so desired, or the screws may be dispensed with and both side members caused to spring automatically open when the toe piece 3 is moved laterally by the engagement of the rider's foot; therewith.

It, will be obvious that the plate 27, which is secured to the toe piece 3 and amends upwardly through a slit in the bottom of the chamber 24, being provided with the laterally extending stud 28 which operates through and is guided by an aperture in the outer wall of said chamber 24, will permit said too piece to be moved laterally in one direction by the en agement; of the rider's foot therewith and in the opposite direction by the coiled spring 29. The lateral movement of the too piece 3 produced by the engagement of the toe of th rider causes the stud 28 to be moved outwardly against the tension of "the spring 29, which forces the pins 21 and 22 out of engagement with the apertured lugs 11 and 12 of the sections 4 and 6 of the foot supporting mem- 65 her whereby said sections are forced apart by the action of the spring 9 and the foot support is thus quickly separated from the hanger and all danger of the rider being dragged is thereby prevented.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, roportion and the minor details of construction may he resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.
